Not bad

Does what it says so no complaints there.

However, it never seems to remember the zoom for the window. When killing the app and re opening it, it would be reset to the default view. Even when playing back recordings after recording, it does the same thing, which is mildly annoying.

On the subject of not saving settings, the app doesn't save settings either across app launches.

The UI for recordings is okay but could be a bit better. Currently, the app pops up a list of actions every time you click on a recording in a list but it's very clunky compared to say... the visual voicemail in the phone app where everything is easily accessible and deleting stuff isn't such a big deal.

Great app, and glad to give the author some money

The original, free SpectrumView was an eye-opener about the way a device like the iPhone could change the landscape of tools: quite unexpectedly, and without spending a cent, I suddenly had in my hand a fair equivalent of a kilo-buck spectrum analyzer; a tool I’d needed from time-to-time over the years, but “knew” I’d never own, or even have access to.

It’s been great that the author(s) have continued to support the tool over the years, and, at some stage, even began extending it. I’m glad to have a number of those extensions, and, in this “Plus” version, to obtain them without the hassle of in-app purchases. Also, after so many years, I’m happy to put some money in the author’s pocket for all that work.

(As to the reviewer who stated that the app has an 8 kHz frequency limit: go to settings and pick an audio sampling rate twice that of the maximum frequency of interest; even my iPhone 5s has no problem reaching 24 kHz. Whether the iPhone microphone is responsive to such frequencies, and equally responsive across whatever frequency range it does handle, is another matter, but that’s what external mics are for.)

It’s the best spectrum app.

This is my favorite frequency analysis app. Incredibly useful and insightful. You can plug your music in or use the mic. A total pleasure to use on drugs. Sometimes it clips when I run my own tracks on it though that’s pretty minor.
